The long, trouble-ridden process of overhauling health insurance hit another snag Tuesday, when the March 31 deadline to sign up for the government's health insurance was extended until mid-April.

The White House cited heavy website volume as the reason Americans may be unable to sign up on the federal exchange by the end of March. Officials expect a high volume of last-minute enrollees, and while they say the website can handle the numbers, they don't want to penalize those who need extra help. The deadline is extended for those who start the process before March 31 but cannot finish it.

Sen. Mike Johanns said that the Obamacare delay is "yet another broken promise by the Administration and further proof that this law should be repealed."

Johanns said the delay counters previous statements by Administration officials that they “don't actually have the statutory authority to extend the open enrollment period in 2014" and that "there is no delay beyond March 31.”

Depending on income, nearly 169,000 uninsured Nebraskans may be eligible for a tax credit when they purchase insurance, according to the Blue Cross-Blue Shield insurance company.

Nebraskans in the 18- to 29-year-old age group need to pay particular attention.

“They can’t just buy insurance if they get sick,” said Tom Gilsdorf, the director of product development for the Blue Cross-Blue Shield insurance company. “Parents of adult children without health insurance should be encouraging their children to sign up. It will give them both peace of mind.”
